OpenSky is a free service provided by Gizmo5 which allows any mobile phone, web browser or IP aware phone network (SIP, asterisk, etc) to communicate for up to 5 minutes with Skype users. OpenSky supports sending text messages and voice calls.
SIP Peering is the term given to agreement between VoIP Service Providers which enables the users of one service to call users of another. This is implemented by dialing a special prefix number and then the number of the receipitant (on the ‘other’ service). For example Ekiga.net users can use the SipBroker’s White page prefixes to call anybody on other SIP networks.
Skype For SIP allows companies to use the Skype service with their IP-enabled PBXs, which use an open standard called SIP or Session Initiation Protocol. Companies using the service can make phone calls from their office phones to any regular phone or mobile phone at the same cheap rates that Skype’s consumer customers can.
